Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the throughput, residual dirt content and degree of fiber loss as variables in the processed product or in the processed product. Concerning methods and equipment for optimizing cotton processing in [Prior art 1] Unlike the previous spinning technology where ring spinning was used as the only yarn manufacturing method, recently it has been developed to New spinning processes are being developed in different directions, which impose different requirements on the permissible wear rate.

These requirements cannot be optimally met by the conventional dust removal methods with regard to the variability of throughput, residual dirt content, and permissible wear of the fibers, as well as their relationship to each other.

The task is therefore to find a solution for optimizing the degree of dust removal taking into account the demands imposed by the spinning method side on the two variables just mentioned.

A point that must be taken into account in this optimization is that the fibers provided to the spinning mill come from different sources.
; It is a mixture made by blending and cutting fibers, and this blending itself is one of the steps to meet the demands for the quality of the spun yarn and the economic requirements considering the price of raw cotton and the price of the spun yarn. This means two optimizations.

The properties of cotton fibers from different origins are related to the fineness, fiber length, strength, extensibility and color of the individual fibers, in terms of natural constraints, and in terms of harvest methods. For example, it is related to the cleanliness or dirtiness of raw cotton.

These contaminants are not only associated with very coarse debris such as metal parts, strings, pieces of cloth, and other foreign objects, but also with the so-called "seed coat fragments".
are also associated with minute cocoon parts, such as other contaminants (dirt) contained within the raw cotton, which place high demands on the dust removers of spinning mills.
Seeds are the everyday dust of the cotton fields and, in a sense, contamination of the cotton by nectar, i.e. sticky sugar substances that adhere to the cotton fibers in the form of fine droplets, which is extremely troublesome for spinning. be.

When dedusting cotton, the room temperature and humidity of the processing space and the moisture content within and on the cotton fibers must also be taken into account.

Furthermore, during the dedusting of cotton fibers, fiber wear occurs due to the extremely aggressive processing, which wear not only shortens the fibers in the first place, but also reduces their strength and extensibility.

Furthermore, during dust removal, many fiber nips, ie, small knot-like structures, may occur to varying degrees depending on the type of machine. This knot-like structure is produced by the tensile movement of the fiber nodules intertwined with each other.

It is clear that when it comes to economical dust removal in textile mills, it is essential to optimize the high throughput desired from a commercial point of view and the careful opening and dust removal desired from a technical point of view. be. The results of this optimization may then vary depending on whether the dedusted fibers are used in one spinning process or in another.

[Problems to be Solved by the Invention] In order to meet scientific and technical requirements, the problems of the present invention are, firstly, to open the fiber bale into fiber agglomerates as small as possible, and secondly, to open the fiber bales into fiber agglomerates as small as possible, and secondly, to The rotational speed and the bale strength of the bale bale roller, together with the knife element and the coding element, are such that the degree of fiber loss occurs only within an acceptable range.

[Means for Solving the Problems 1] The constituent means of the present invention for solving the above-mentioned problems are as follows: (a) On the one hand, the fiber characteristics originating from the production area of raw cotton and the ratio of various dart species are inputted into the control unit as starting data; (b) On the other hand, the desired degree of dust removal and the processing amount of carded sliver are input into the control unit, and (c) a predetermined type of signal is generated based on the input starting point data, the processing amount and the processing amount of the carded sliver. configuring said control unit to send out a signal of the predetermined type, and setting adjustable working elements which effect the degree of opening and dedusting of the corresponding bale opener, deduster or card, and thus the dedusting to be performed. The object of the present invention is to obtain the desired degree of dust removal and throughput of the carded sliver while displaying the estimated degree of fiber loss of the cotton fiber.

Another element of the solution according to the invention is that the calculated degree of dust removal is checked by means of sensor means in the dust discharge chamber of the dust remover or is monitored during operation and, if necessary, corrected automatically. .

[Function] The advantage obtained by the invention is that the dust removal strength can be adapted to the requirements, thereby reducing the purity and fiber loss of the carded sliver and the amount of work (m/m) for producing said carded sliver. (min) can be made into an optimal mutual relationship.

[Example] Next, embodiments of the present invention will be explained in detail based on the drawings.

A fiber mass is cut out from a fiber hale 2 by a bale opener 1, and is supplied to a first dust remover, for example, a rough dust remover 4, via a conveyance path 3. On the way of the conveyance path 3, it is possible to detect the amount of conveyed fiber mass per unit time, for example, m3/h, by a measuring device 54. However, this quantity measurement is not limited to this example, and it is also possible to transport this fiber mass in direct connection with the bale opener 1, i.e. to omit said measurement completely and to store it above each dust remover as described below. It is also possible to provide a section.

Incidentally, the dirt (contaminants such as dust) is separated in the coarse dust remover 4, which will be described in detail later, and the fiber lumps, which have been previously removed and whose size has already been significantly reduced, are transferred to a second dust remover via another conveyance path 5. , for example, is supplied to the fine dust remover 6, and the first
The dust is removed more powerfully than in the coarse dust remover 4, and then the dust is transported to the 7-ide device 8 via another transport path 7.

From the feed device 8 the fiber wrap 9 reaches the card 11 via a chute IO.

The carded sliver 12 from the card 11 is transferred to a can coiler 13.

Next, the individual devices will be explained.

The bale opener l, which is a bale opening machine widely sold by the applicant under the trade name 'υNIFLOC'', is known per se and therefore only the points that are important for understanding the invention will be mentioned here. I kept it at.

Such a bale opener 1 has at least one scraping roller 14, and the scraping roller scrapes the fiber mass from the upper surface of the fiber veil 2 when reciprocating in the direction of the arrow 15, for example by pneumatic pressure. is transferred via the conveyance path 3.

In that case, the 7 eid speed in the moving direction 15, the penetration depth 61 of the scraping roller 14 into the upper surface of the bale, the circumferential speed of the scraping roller, and other immutable parameters are determined by the scraping work (Kg/h) and Determine fiber mass size.

The coarse dust remover 4 has a dust removal roller 16, and a plurality of beater spikes 17 are fixed to the circumferential surface of the air removal roller. The beater spike conveys the fed fiber mass onto a grid bar 18 in a known manner, which grid bar is arranged over a portion of the circumference of the dust removal roller 16. The position of the grid bar can be adjusted, and the dust removal strength can be varied by this adjustment.

This variability is illustrated schematically by the dash-dotted line l9.

The brightness sensor 20 also measures the brightness, or the ultrasonic sensor measures the reflected sound, as a measure of the dirt content in the separated ejecta, which is separated through the grid bar and placed in the collection hopper 2l. This is the waste that is collected. The collecting hopper 2l is composed of upper and lower parts, and the lower part 22 is movable relative to the upper part 23 and is supported on a plurality of pressure measuring cells 24.

The lower part 22 thereby becomes a weighing container for the reservoir of the discharged material. The discharged material is sucked out via the suction conveyor 55 at predetermined time intervals. During this suction time, weighing of the emitted product is interrupted. The amount of emitted material can also be determined indirectly by means of a light barrier via volume measurements per unit time and taking into account the variable density as a function of the dart fraction.

The fine dust remover 6 has a dust removal roller 25 optionally equipped with a serrated cloth or other cloth for opening the supplied fiber mass into finer fibers than in the coarse dust remover 4 described above. ing.

The fiber mass is then fed to the dust removal roller 25 by means of a feed roller 26 and a feed plate 27 which cooperates with the feed roller and is pivotable about a pivot axis 50 . Since the function of such a feed device is known per se, a detailed explanation will be omitted, but it should be noted that the feed plate 27 is pressed toward the feed roller 26 with a predetermined force, and the rotation axis 50 is the feed roller 26
It is possible to turn a predetermined amount in the directions of arrows S and 5.1 about the rotation axis 5l, and this is represented by a turning radius R. This pivotability allows the feed fiber nip line between the feed roller 26 and the fiber delivery edge 52 of the foot plate 27 to be sheared along the circumference of the feed roller 26, so that the short fibers teeth,
The long fibers are fed by shifting the nip line further forward as seen in the fiber transport direction, and the long fibers are fed by shifting the nip line further back. By this measure, fiber shortening during feeding is completely avoided, unlike in the case of fixed nip lines.

Instead of a spring-loaded feed plate, it is also possible to spring-load the feed roller towards the feed plate. In such a case, the feed plate moves on a fixed orbit (
(not shown).

The fiber mass supplied to the dust removal roller 25 is captured by the dust removal roller and guided along a plurality of dust removal elements 28 arranged around a portion of the circumferential surface of the dust removal roller 25.

The dust removal element may be a plurality of carding elements or a plurality of knives with or without a guide plate.

Furthermore, the dust removal element is designed to be able to change its dust removal strength. The variability of this dust removal strength is schematically indicated by a dashed line 29.

Similar to coarse remover 5, there is a small amount of dust [6 is also at the bottom, upper part 2
It has a collection hopper 21.1 for receiving the discharge, which is divided into a lower part 22.1 and a lower part 22.1. In this case too, the collection hopper 21,1 is supported on the pressure measuring cell 24.1 as described above. Similarly, the brightness sensor 20. The brightness is measured by a suction conveyor 55.
It is sucked out by 1. In this case as well, it is also possible to use an ultrasonic sensor instead of a brightness sensor, or to perform capacitance measurement instead of weight measurement.

The dashed-dotted rectangle 30 indicates that another dust remover or a machine having a dust removal function equal to or similar to the fine dust remover 6 can be provided; that is, the present invention is not limited to the illustrated combination of dust removers. It is not something that will be done.

7 The eid device 8 has a charging cylinder 3l and two feed rollers 32, which feed the fiber mass to an opening roller 33, by which it is additionally reduced in size, i.e. further The fibers are opened.

These finely opened fiber masses are fed to the lower supply cylinder 3.
4, and then carried out by two feed rollers 35, compressed between one of the two feed rollers 35 and a pressure roller 36, and formed into the already mentioned fiber wrap 9. , the fiber wrap is then guided over the chute 10 towards the feed rollers 37 of the card 11.

Furthermore, the fiber wrap 9 is fed in a known manner from a feed roller 37 to a licker-in roller 39 with a toothed cloth, which opens the fiber wrap 9 into thin fiber 7 wreaths and feeds them into the main cylinder. Although the carding operation for feeding the licker-in roller 40 is known per se and will not be described in detail here, the licker-in roller 39 can have a dust removal element 41 on a part of its circumference, the dust removal strength of which can be adjusted. I would like to add this. The adjustability of the dust removal element 41 is indicated schematically by a dash-dotted line 42.

The dust removed by the dust removal element 41 is finer than that of the fine dust remover 6, ie the dust removal strength of the dust removal element 41 is adapted accordingly.

A pressure measurement cell 58 is used to collect and measure the emissions.
A weighing pan 59 supported above is provided, which weighing pan is connected to a suction conveyor 60 . The actual dirt content in the effluent is measured by a brightness sensor 20.2 or by a suitable ultrasonic sensor and by a suction conveyor 55;
5.1 and periodically aspirated in accordance with 5.1.

The fiber fleece resting on the main cylinder 40 is received by a dosing roller 43 and between the downstream roller and the 7-lease press 44 the above-mentioned carded sliver 12 is removed.
be squeezed into The carded sliver 12 is further tested in a measuring trumpet 46 for the micronaire of the carded sliver 46 . Following the measuring trumpet 46, a measuring roller pair 47 sends out the amount of fiber sliver per unit time (m/min) as a signal 5.47, which will be described later.

Finally, the curd sliver 12 is removed by the Kenscoiler 13.
The color of the sliver is checked by a color sensor 48 before being loaded into the sliver.

The optimization of said operation is carried out by the microcomputer control unit 53. In the microcomputer control unit, the above-mentioned starting point data, that is, fiber length (staple length) -St, fiber fineness = M, strength = F, elongation = D, and the measured or verified coarse dirt ratio = GR and fine dirt ratio. Fiber properties such as FH are entered per fiber bale or as an average value of the entire fed bale pattern calculated external to the control unit.

When inputting starting point data per fiber bale, the control unit itself calculates the average value. Furthermore, the degree of dust removal of the product = RG, the product processing capacity, that is, the amount of work 1 L (Kg/h
) and the possible degree of wear and tear of the fibers (FB). For these three variables, it is possible to give each variable priority over the other two variables respectively.

It is also possible to give priority to two variables in common over a third variable.

Said priority is established by input to the control unit. In principle, the desired amount of work and the desired degree of dust removal are input with priority, and the computer adjusts the work elements based on the input starting point data and the input dirt ratio. While the values are calculated, displayed and/or automatically set, the possible wear and tear of the fibers calculated from the adjusted values is also displayed.

In that case, the operator can accept these adjustment values, or if not accept them, he can also modify the values for the degree of dust removal and the value for the amount of work; each time this modification is made, the computer Immediately and upon new adjustment of the working elements, a new value of the possible degree of wear of the fibers will be calculated. The above operations of the computer are repeated until the three variables display acceptable values. This is the case for fixedly defined feed fiber veil patterns with average values calculated from the origin data. The determination of acceptability of the values of the three variables is related to the type of yarn to be produced or the type of yarn used.

In one variable, the computer is programmed by additionally inputting the type of yarn used. This input (not shown) is input with the priority of No. ①, and the degree of dust removal and the degree of fiber wear are substantially determined by this, so if the starting point data and dirt ratio have been determined, , the amount of work calculated therefrom must be accepted.

In other variables, the feed fiber bale pattern is adapted by selecting other bale origins until the three variables are within acceptable ranges based on the new origin data.

This can in some cases be done by recalculating said average value of the individual starting point data and inputting these starting point data into the computer.

In other cases, i.e. with other variables, the computer is set to input the origin data of each bale origin into the computer by selecting from the bale origins, and the computer is configured to input the origin data of each bale origin into the computer; The bale production area itself can be selected by inputting the degree of wear or the type of yarn used and the amount of work. These inputs of origin data are performed using the keyboard described below for each production area.

Regarding such bale origins, which can be graded in different variations, reference is made to the Swiss Patent Application No. 03335/88-8 by the same applicant.

Another additional variable is the cost of each fiber bale origin (not shown) inherent in the fiber bale pattern, as well as the ability to maintain profit margins within a given range if tolerances for purity and fiber attrition are large. The point is to enter a predetermined value indication for the yarn to be produced in order to reduce or accept a profit margin where tolerances regarding purity and fiber wear are normal.

However, this presupposes that new priorities have to be set regarding profit margins, purity and fiber wear. This is because setting this priority requires a corresponding decision by operating personnel.

The entry of starting point data, dirt species ratio, degree of dust removal, throughput and estimated fiber loss is carried out via a suitable digital keyboard or analog switch (e.g. potentiometer), which is designated by the abbreviation St in the drawings. ,M,F,
They are simply indicated by D, GR, FR, RG, L and FB. The inputs to the control unit are input signals st, m,
This is done via f, d, gr, fr, rg, l and fb. In that case, the input signals rg, l and fb are input to the display A. R.G., A. L and A. Displayed on FB, for example, the amount of work L is Kg/h
In units, the dust removal degree RG is expressed in %, and the estimated fiber wear degree (
(expressed in the form of shortening of the fiber length in practice) is the fiber length S
It is expressed as a percentage of t.

From these data just mentioned, the computer (microcomputer) calculates adjustment values for the reservoirs of the working elements and displays these adjustment values in each case on a corresponding display.

In relatively simple variant embodiments, operating personnel operate the adjustment of the working elements, whereas in the case of "automatic operation" this adjustment is activated by a computer.

Next, an example of "automatic operation" will be explained.

For the bale opener 1, the microcomputer control unit 53 sends an output signal S. 14 is sent. The rotation speed is displayed on display A. Displayed in l4. The second output signal S. 15 determines the feed speed of the reciprocating feeder 15 of the bale opener l and displays the display A. At l5, the feed speed is displayed, for example, in units of m/min. The third output signal 3.16 determines the penetration depth per unit area of the scraping roller 14. The penetration depth per unit area means the penetration depth at the start of cutting. This is because the penetration depth is varied during milling based on the machine's own control, since the density of the fiber veil varies depending on the remaining height of the fiber veil. Such control is described in European Patent No. 19
No. 3,647. It is clear that if said variables are given and/or the bale locality is automatically selected by the computer, a signal for the penetration depth per unit area per bale locality is emitted by the computer. .

For the coarse dust remover 4, the microcomputer control unit 53 outputs an output signal S. 16 and S. The output signal 5.16 controls the rotation speed of the dust removal roller 16 and displays the display A.19. 16, whereas the output signal S. l9 causes an adjustment of the grid par 18 and displays the adjustment on display A.19. For example, the angle value is displayed at l 9 .

The brightness of the separation layer measured by the brightness sensor 20 is input as an input signal 5.20 to the control unit 53 and output to the display A.20. Displayed at 20. Similarly,
The weight ascertained by the pressure measuring cell 24 is input to the input signal S
．． 24 to the control unit 53 and displayed on the display A.24. 24. Since the measurements are then carried out during a predetermined interval, the indicated weight corresponds to the sum of the emissions occurring during this interval.

The same thing as the coarse dust remover is done in the fine dust remover 6,
In that case, the computer of the control unit 53 displays the rotation value of the dust removal roller 25 on the display A. 25 and produces a corresponding rotational speed with the output signal 3.25, whereas the adjustment value of the dust removal element 28 is displayed in the display A.25. 29 and adjusted by the output signal 3.29. In that case display A. The designation 29 relates to the type of dust removal element 28. For example, in the case of a dust removal element whose dust removal strength can be adjusted, it is possible to display the dust removal strength in %.

Brightness sensor 20. l is the input signal S.l which corresponds to the brightness of the separated emissions. 20.1 to the control unit 53, and the input signal is transmitted to the display A.20.1. 20.1, and also the input signal S.20.1 from the pressure measuring cell 24.1. 24.1 is display A. 24.1. Similar in form to the coarse dust remover 4, the discharged material in the fine dust remover 6 is also transferred to a weighing container (
22.1) The weight signal S. 24.1 to the control unit 53.

The fine dust remover 6 also has a signal 3.50, which is sent by the control unit 53 and causes the pivot shaft 50 to assume the correct position in accordance with the fiber length of the fibers to be processed.

7 The rotation speed of the opening roller 33 in the eid device 8 is determined by the signal S.7 from the control unit 53. Although controlled by 33,
In this case, the control by this signal is optional and is indicated by a dashed line.

The workload of the entire plant is primarily forced by the workload of the card 11 and moreover by the rotational speed of the feed roller 37. As already mentioned, this amount of work is
is input to the control unit 53 by a signal l from the display A. L and the signal S.L. 37, or by giving a priority as already mentioned, it is simply indicated according to this given priority and a corresponding calculation, adjusted accordingly;
That is, the signal S. 37 is automatically generated.

The workload of the plant can also be checked by a measuring device 54 in the conveyor path 3, which detects the amount of fiber mass cut out by the bale opener l per unit time and is controlled by a signal 3.54. input to the unit and display A. 54.

When products transported from machine to machine in a plant are processed continuously without providing a storage tank above the dust remover, the workload is monitored by the card 11 and the measuring device 54 in the rough dust remover. This is indispensable in combination with the monitoring of the separated emissions in the dust remover 4 and the fine dust remover 6. The m removal machine has stopped.
/Go method, a storage tank is provided above the dust remover.

However, even in the case of the Stop/Go method, it is advantageous to monitor the workload using the measuring device 54. This is because this monitoring makes it possible to minimize the downtime in the Stop/Go mode of operation.

The storage tank corresponds to the feed device 8 without the pressure roller 36.The Stop/Go operation is performed using the light barrier 56.
57, the light barrier is controlled by the lower supply tube 3
detecting the level of fiber agglomeration within 4;
The leading machine on the fiber mass travel path is a light barrier 56.
It is turned off at the level of the write barrier 57, and turned on again at the level of the write barrier 57. The more accurately the workload monitoring by the measuring device 54 and the emission monitoring by the pressure measuring cell 24, 24.1.58, the more accurately the dust remover is switched on and off.
It is obvious that the FF switching frequency decreases.

The detection results of the write barriers 56 and 57 are the signals S. 56, S. Control unit 5 by 57
3 is input. However, in this case, the broken line does not reach the control unit 53 because it is not displayed on the display.

Another possibility for monitoring and removing dust from the fibers to be processed is, as already mentioned, to use in the card 11 a dust removal element 41 whose dust removal strength can be adjusted, and the possibility of adjusting the dust removal strength is indicated by the dot-dashed line 42. It is implied in

The dust removal strength of the dust removal element 41 is determined by the signal S. It is transmitted to the dust removal element 41 via 42. The emission brightness measured by the brightness sensor 20.2 is input by the signal 20.2 and the weight measured by the pressure measuring cell 58 by the signal 3.58 to the control unit 53, which displays the display A.
．． 2 0.2; A. Displayed as 5 8.

Since the amount of work of the card 11 is determined not only by the feed roller 37 but also by the doffer roller 43, the number of rotations of the doffer roller is determined by the number of rotations of the doffer roller 43 from the control unit 53. 43 and display A.43. 4
3 is displayed.

The fiber fineness of the carded sliver at the exit of the card 11 is determined by the signal S from the measuring trumpet 46. 46 to the control unit 53 and a corresponding display A. 46 is displayed. This measurement represents one check of the supply bale pattern, ie a check of the correct combination of bale origins.

The card-specific card sliver throughput (rR/h) is measured by a measuring roller pair 47 whose signal 5.47 is displayed on the display A, 47 and input to the control unit 53. Feed roller 37
The difference between the amount supplied according to the rotational speed by the measuring roller pair 47 and the amount confirmed by the measuring roller pair 47 is determined by the force 11.
Dirt and short fibers separated by 1.

Checking the total blending and opening/dedusting progress of the bale production area is also carried out by checking the brightness of a color sensor 48, which detects the carded sliver 12 with respect to its color and/or brightness and outputs a signal S. ．． 48 to the control unit 53 and display A
．． 48 is displayed. This check is not about the dust-removal effectiveness of the preceding machine, but about the correct formulation of the basic color of the fibers, i.e. the feed bale pattern. If the color tone is not adapted during this check, an alert will be issued informing the operator if the automatic selection of the supply bale pattern should be discontinued, or else the computer will decide to change the supply bale pattern. A tone check of the basic fiber colors is only possible at the color sensor 48. This is because the fiber material has not yet been completely dusted before this point.
This is because even if the color tone is checked during the passage of the fibrous material in such an incompletely dusted state, only erroneous detection results will be obtained due to the residual dust.

The temperature and humidity of the processing space are also taken into account for said optimization, and the display A. T;A. It is displayed as Fe.

The difference between the embodiment shown in FIG. 2 and the embodiment shown in FIG. 1 is as follows.
A plurality of fiber bales are identified by production area codes A, BC, D, and E, and a predetermined interval Z, which will be described later, is provided between the fiber bales.

The fiber lumps cut out by the bale opener l from the individual fiber bales classified by production region reach the coarse dust remover 4 via the conveyance path 3, and from there via the transport path 5.1 to the individual bales storage section 63 classified by production region. reach.

Since there is one storage section for each production region, they are identified by the same production region symbol as the fiber bale. Even when a plurality of fiber bales 2 from the same production area are arranged in parallel, it is advantageous to provide one fiber storage section 63 for each fiber bale 2 in order to obtain more homogeneous blending. be.

The conveying path 5.1 is provided with a branch 62, so that the partial storage 63 can directly control the charging. In the case of pneumatic conveyance in such a branch section 62, each component storage section 63, which is a so-called duct rolling device, has a pair of scraped rollers 64, and by the pair of scraped rollers, the component storage section is The existing fiber mass is cut out and transferred to the conveyor belt 65
sent upwards. On the conveyor belt 65, the fiber mass coming out of all the partial stores 63 is collected in overlapping layers, as can be seen in FIG.
, for example towards a small conveyor belt, which conveyor belt 65 together with the squeezing element 66 feeds the entire fiber layer to a spreading element 67 having opening rollers 68 . The opening element 67 and the drawn air flow 6
9 transports the fiber mass through a transport path 70 into the fine dust remover 6.

In a variant embodiment (not shown) in which the fine dust remover is provided directly below the squeezing element 66, the fiber layer can be fed directly to the fine dust remover 6.

The control unit 53.1 uses the control unit 53 for calculations.
It also has a built-in microcomputer, but data on the origin of fibers, which are restricted by the nature of each production area, is input into the control unit, and the computer controls the work elements of the coarse dust remover 4 for each production area. It is also possible to make it adjustable.

In order to obtain time for the adjustment of the working elements in the coarse dust remover 4 without having to stop the bale opener l at the fiber bale of the individual source, the spacing Z has a corresponding defined value. . Adjust the position of the work element by cutting out the fiber mass in only one direction of movement, or
Or it can be carried out in only one direction of movement of the bale opener I or in both directions of movement, depending on whether it is carried out in both directions of movement.

The measuring device 54 for monitoring the machining efficiency of the bale opener 1 has the same function as in the embodiment shown in FIG. This is because the light barriers (photocells) 56 and 57 in the bulk storage section 63 are provided only for safety purposes, such as to notify of supply trouble or supply amount trouble. Therefore said photocells 56 and 57 are also connected to the control unit 53.
1 (not shown).

Needless to say, the cutting efficiency of the pair of cutting rollers 64, the conveyance output of the conveyor belts 65, 66, and the rotational speed of the opening roller 68 are controlled by the control unit 53.1.

Other components having the same reference numerals as in FIG. 1, which will not be described again, function in the same manner.

The advantage of the embodiment shown in FIG. 2 is that the dust removal of the fibers from each origin can be differentiated, and it results in a more homogeneous blending of the individual origin fibers.

The difference between the embodiment shown in FIG. 3 and the embodiment shown in FIG. 2 is as follows.
Before the individual fibers are transported to the storage section 63, they are removed by a fine dust remover 6. The fiber mass is therefore conveyed from the fine dust remover 6 via the branch 62 to the filtration storage 63 by the discharge path 7.1. After pre-blending the locally sourced fibers, the fiber mass is fed to the feed device 8 via a conveying path 70 following the opening element 67.

The control unit of this embodiment is designated by the reference numeral 53.2.

Other structural elements with the same reference numbers as in FIG. 2, which have not been re-explained, function in the same manner.

The advantage of the embodiment shown in FIG. 3 is that the fiber mass of the individual sources can be dedusted before blending with a coarse dust remover as well as with a fine dust remover.

As already mentioned above, it is of course possible to supplement the control unit and the processing plant with respect to the number of fiber cuttings and the number of fiber blendings, if fibers from other sources have to be involved in order to meet the requirements of the yarn to be spun. It is.

Finally, it should be noted that this type of control is not limited to the use of integrated plants, but is also used in the textile sector for working elements for changing products and for monitoring to check these changes.
